A self-aligning steering system for a vehicle having a steering wheel and a plurality of front wheels. The invention has a hydraulic fluid circulation means responsive to the steering wheel and a left and a right hydraulic cylinder for maneuvering the front wheels in response to the hydraulic fluid circulation system. The hydraulic cylinders have an internal fluid release system such that the volume of hydraulic fluid in the left and the right hydraulic cylinders is equalized through the hydraulic fluid circulation means. Equal hydraulic fluid volume ensures that the front wheels are in alignment.
